The Subzone Loader (SZL or "Sizzle") allows you to visualize large data files on typical engineering workstations by loading only the data required for a particular operation. Unlike the previous load-on-demand capability, Subzone Load can load partial zones instead of entire zones. This capability requires a new file format, .szplt, which can be loaded using the Tecplot Subzone Loader.
Data can be converted to the .szplt format manually, by loading it into Tecplot 360 EX and then writing it in SZL format (see Section 23 - 2 “Data File Writing”). For information on batch-converting files to SZL format, see Section 27 - 5 “Batch Converting to SZL Format”.
The Tecplot Subzone Loader is used for loading .szplt files stored on your local disk or on a standard network share (that is, a share that is supported by your computer's operating system). To load files from a Linux remote host on which Tecplot SZL Server is installed, see Section 4 - 29 “Loading Remote Data using Tecplot SZL Server”.
